AMD's latest enthusiast chipset adds support for the upcoming Bulldozer AM3+ processors. In other respects it is pretty much the same as last year's 890FX – with 32 PCIe lanes that can be split into x16/x16, x16/x8/x8 or x8/x8/x8/x8.

AMD A75

The A75 is AMD's newest FCH (Fusion Controller Hub). Unlike the very first A50 FCH, these are designed for use with standard desktop processors using the new Socket FM1. It appears that the A75 will natively support 4 USB 3.0 ports (it has already gained USB-IF certification), in addition to six SATA 6Gbps ports.
